Some
Interesting Demonstrations
The intention
of these scenarios is to demonstrate how data and services
provided by CEOS agencies can be used to solve real problems.
Prototype scenarios are listed below, and more will be added,
as they become available.
Multi-scale
Burned Area Mapping (Canada) through CCRS
The tools demonstrated here can be used to link information
from annual burned area maps derived using 1-km resolution
SPOT VEGETATION and NOAA/AVHRR imagery with browse imagery
from the Landsat-5 TM and Landsat-7 ETM+ sensors, which have
a resolution of 30 metres. By clicking on an individual burn
polygon, users can find the first and last dates that a fire
was detected based on an AVHRR monitoring system, such as
FireM3.
This information may then be used to locate Landsat imagery
acquired before and after those dates. Appropriate scenes
can then be ordered for detailed analysis.
Access
to Global Datasets of Landsat 7
This tool demonstrates a distributed access search engine
linked to geographical places. The system uses a browser on
your desktop to establish a search query. The resulting browse
products are retrieved through a TRIFC gateway from the US
National archives.
